1. What happened
When an ImageTarget gameObject is duplicated, and the Image Target on the Image Target Behavior script is changed on the duplicate, the Scene view will show both Image Target gameobjects having the same Image Target.

Steps To Reproduce:

1) Create a new project
2) Enable Vuforia in the player settings
3) Add an ImageTarget to the scene (it will default as astronaut)
4) Make a duplicate of the image target, move it so they are side by side in the scene view
5) Change ImageTarget(1) in the Image Target Behavior Script component to Drone
6) Click between the two Image Target gameObjects, notice the Scene view changes each time so that both show the same Image Target. Clicking on IMageTarget will make both show Astronaut, while clicking on ImageTarget(1) will make both show the Drone

Expected Result :
No change in preview of Image Targets in Scene view.

Actual Result :
Change in preview windows of Image Target.

Frequency:
Always
